Market Overview

The global stem cell therapy market for neurodegenerative diseases is projected to grow from approximately $1.2 billion in 2024 to $4.5 billion by 2035, representing a compound annual growth rate (CAGR) of approximately 12%. [2](https://doi.org/10.1016/j.nbd.2023.105858) [@ipsc2020]

Key Growth Drivers

• Aging population: Rising prevalence of neurodegenerative diseases in aging populations
• Limited treatment options: Current therapies only manage symptoms, not disease progression
• Advances in iPSC technology: Induced pluripotent stem cell technology enables patient-specific therapies
• Regulatory support: Accelerated approval pathways for cell therapy products

• Allogeneic iPSCs: "Off-the-shelf" products from master cell banks
• Gene editing: Correction of disease-causing mutations in patient-derived iPSCs

Embryonic Stem Cell (ESC) Derivatives

• Dopaminergic neurons: For Parkinson's disease (clinical trials ongoing)
• Motor neurons: For ALS
• Retinal pigment epithelium: For macular degeneration

Mesenchymal Stem Cells (MSCs)

• Immunomodulation: Suppression of neuroinflammation [4](https://doi.org/10.1186/s13287-021-02255-3)
